Protect Every Tenant. Every Server.
Commercial surge events — from HECO grid switching, lightning, generator transfer, or internal load events — can take out servers, POS systems, HVAC controls, refrigeration, and tenant equipment in milliseconds. The replacement cost (and downtime) of even one bad surge dwarfs the cost of proper SPD installation.
Sparky and Sons installs commercial-grade surge protection systems — Type 1 service-entrance SPDs for the highest tier of protection, Type 2 panel-level SPDs for distribution panels and sub-panels, and point-of-use protection for sensitive critical equipment.
For multi-tenant buildings, we offer a layered approach: building-wide SPD at main service, tenant-level SPD on each tenant’s sub-panel. Each tenant gets a clean, surge-protected feed.
